The team who fixed our support beams/foundation was wonderful. I can't say enough good things about Freddy ********* Walter ********* and Jaime ***** who did the repairs: they were friendly, timely, and did wonderful work. Also, the permit team at JES really helped us when we still hadn't received word from the city and it had been 6 weeks (and my husband and I had been sleeping on the couch and floor because the support beams were so bad under our room). Thank you to the entire team!

4 star due to scheduling issues I had and having to call to get the work completed.Joe Crossfield/David Gaskins/Larry and crew were great.Joe was the sales guy that came out to quote us for the work. He was very polite and was honest about what needed to be done. He didn’t upsell us on any add ons and helped us save a little bit of money by offering alternatives for the encapsulation project.Larry and crew: they came and did the work and did a great job. Cleaned up after themselves and completed the work. Not sure if it was the day or the overwhelming work the crew had, but I felt like I was rushed when I asked questions and felt like an inconvenience when I did asked questions. So I didn’t appreciate that.David Gaskins: was polite and explained how to clean the dehumidifier and all that. Explained what the RH% should be in the crawlspace and showed me how to work the dehumidifier. I originally called because I wanted my encapsulated crawlspace to be at 40% RH but it wasn’t getting there. He explained to me that it is possible for the machine to get down that low but explained the issue that I may have with my foundation and wood beam. He was very honest and did not rush me when I was asking the questions.Cons:-After paying the deposit, I had to give the office a call to schedule my appointment. I would think that they would call me to schedule and get it on the books, but that did not happen.-the scheduler scheduled the encapsulation, but not the electricians subcontractor. You would think that they should schedule the electrician first before the work so that the work is totally complete once the crew comes. I ended up calling the office, getting the phone number to the electricians, and calling the electricians myself to get something scheduled since the office could only email the subcontractor to be put on the books.

Had JES come out and install a box drain. Darrell M. The job supervisor called me early that morning to let me know what time he was coming. He greeted me and introduced himself and his crew, Ricky J. And Allen B. He told me what he was going to do and asked if I was ok with what he was going to do. They got right to work. When they were finished, he knocked on the door and showed me what he'd done. The job was done beautifully, and the clean-up was too. I'm very pleased with the work. And would use them again

We think Max was terrific! He explained everything very well, made sure we were comfortable with everything, before jumping into what the job would cost. Explaining the cost benefit was very enlightening. We couldn't be more happy.

Andre Williams provided excellent service for the annual maintenance of my drainage system. He shared his knowledge about the importance of controlling the humidity level in my basement and the criteria for judging whether a dehumidifier is needed. He brings a wealth of knowledge and experience to his work and he shares it in a friendly and informative manner.
